Dora the Explorer, eponymous Latina star of the animated Nickelodeon series, is a bilingual problem solver who confidently traverses unknown territory in every episode. In “City of Lost Toys,” a typical episode, Dora sets out to find her missing teddy bear, Osito, and other toys her friends have lost. She’s helped along the way by her sidekick (a monkey named Boots), her trusty map, and a group of magical stars she and Boots catch. The first landmark Dora reaches on her journey is a Mesoamerican-style pyramid where she must complete basic counting and arithmetic problems.
